Explanatory Note

                    This Current Report on Form 8-K/A is being filed as an amendment ("Amendment No. 1") to the Current Report on Form 8-K filed by the Corporation with the Securities and Exchange Commission on April 20, 2011 ("Original Filing"). The sole purpose of this Amendment No. 1 is to disclose the decision of the Company regarding how frequently it will conduct non-binding shareholder advisory votes on the compensation of executives. No other changes have been made to the Original Filing.

                    At the Company's 2011 annual meeting of shareholders, the Company's shareholders voted on, among other matters, a proposal regarding the frequency of future non-binding shareholder advisory votes on the compensation of the Company's named executive officers. As previously reported by the Company in the Original Filing, a majority of votes cast on the frequency proposal were cast in favor of holding an advisory vote on the compensation of executives every year. In light of such voting results, the Board of Directors has determined that the Company will hold an advisory vote on the compensation of executives every year until the next required vote on the frequency of shareholder votes on the compensation of executives.
